Re: Milling the head
I had a Model "B" head milled 0.090" which left about 0.010" depth of the piston pockets, and 0.03" clearance to the pistons. The compression increase was not competitive with a 5.5:1 cylinder head.
Occasionally, carbon buildup on the pistons would cause a horrible knock as it hit the head.
It is difficult to set the head up for milling such that the remaining material from the deck surface to the piston pockets are equal.
I would not do it again!
